The TMS320C55x (C55x) External Memory Interface (EMIF)supports a glueless interface to high-density and high-speed SDRAMs. Both 64-Mbit and 128-Mbit SDRAMs are supported in 16-bit and also 32-bit data widths. The DSP can also provide the SDRAM clock at software selectable submultiples of the C55x DSP CPU frequency. This application report presents the C55x EMIF signals and the necessary signal connections between the DSP and various types of SDRAM. EMIF register bit settings are also discussed.……
